Estus Flask Shards are given to the Emerald Herald in Majula to increase the total amount of Estus Flasks that the player can hold. They can be upgraded to a maximum of 12 flasks. The shards can still be obtained after the player increases up to 12, but will be useless (although they can be sold to Lonesome Gavlan for 1,200 souls each).

After the second bonfire and past the Ogre, there is a narrow path along the pillars. The shard is found on a corpse past two Amana Sorceresses. The Sunlight Blademiracle can also be found in a chest not far from the corpse.
